BACKGROUND & AIMS: Neonatal sclerosing cholangitis (NSC) is a severe neonatal-onset cholangiopathy commonly leading to liver transplantation (LT) for end-stage liver disease in childhood. Liver-biopsy findings histopathologically resemble those in biliary atresia (BA); however, in NSC extrahepatic bile ducts are patent, whilst in BA their lumina are obliterated. NSC is commonly seen in consanguineous kindreds, suggesting autosomal recessive inheritance. METHODS: From 29 NSC patients (24 families) identified, DNA was available in 24 (21 families)...

Neonatal sclerosing cholangitis (NSC) is a rare biliary disease leading to liver transplantation in childhood. Patients with NSC and ichtyosis have already been identified with a CLDN1 mutation, encoding a tight-junction protein. However, for the majority of patients, the molecular basis of NSC remains unknown. We identified biallelic missense mutations or in-frame deletion in DCDC2 in four affected children. Mutations involve highly conserved amino acids in the doublecortin domains of the protein. In cholangiocytes, DCDC2 protein is normally located in the cytoplasm and cilia, whereas in patients the mutated protein is accumulated in the cytoplasm, absent from cilia, and associated with ciliogenesis defect...

OBJECTIVE: Pruritus is a common symptom of cholestatic liver disorders. The present study aimed at evaluating autotaxin (ATX), a lysophospholipase recently identified as potential cause for cholestatic pruritus, in pediatric cholestatic diseases presenting with or without itching. METHODS: A cohort of 45 children consisting of 14 patients experiencing itching (Alagille syndrome [n = 10], complete extrahepatic biliary atresia [n = 2], neonatal sclerosing cholangitis (n = 1), progressive familial intrahepatic cholestasis type 2 [n = 1]), 9 patients with bile acid synthesis defects (3β-hydroxy-C27-steroid-oxidoreductase [n = 7] and Δ-3-oxosteroid-5β-reductase deficiency [n = 2]), and 22 healthy children were studied...

Primary sclerosing cholangitis is a progressive disease, and coincidentally in pregnancy it is rare. It is characterized by progressive inflammation and destruction of bile ducts finally resulting in liver failure. A rare case of primary sclerosing cholangitis in pregnancy is presented. The course of the pregnancy was marked by threatened preterm delivery and exacerbation of cholestasis. She was successfully treated with ursodeoxycholic acid (UDCA). Although, primary sclerosing cholangitis has both maternal and fetal effects on pregnancy, the overall outcome is favorable...

BACKGROUND & AIMS: Studies of primary sclerosing cholangitis (PSC) and pregnancy outcomes have been limited in size and have been inadequate to rule out excess risks. We examined pregnancy outcomes among women with PSC. METHODS: Women with PSC were identified from inpatient and hospital-based outpatient data in the Swedish National Patient Register. Through linkage with the Medical Birth Register, we identified 229 singleton births, from 1987 through 2009, to women with PSC before delivery...

Congenital biliary tract anomalies typically present with neonatal cholestasis. In children and adults, endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound are used to evaluate and treat choledochal cysts. Contrarily, endoscopy has traditionally played a minor role in the diagnosis of the cholestatic infant. Recent studies support the incorporation of ERCP into the diagnostic algorithm for biliary atresia and neonatal cholestasis. But at present, most pediatric liver centers do not consider its use essential...

Follicular carcinoma of the thyroid is a relatively rare malignancy in childhood even in paediatric solid organ transplant recipients. The risk of developing de novo malignancies after liver transplantation is higher compared to the general population. We report an 18-yr-old girl who had successfully undergone liver transplantation five yr earlier for neonatal sclerosing cholangitis complicated by the development of dysplastic nodules. Baseline immunosuppression was with tacrolimus and prednisolone. Mycophenolate mofetil was later added in view of steroid-resistant episodes of graft rejection...

Sclerosing cholangitis (SC) is a chronic cholestatic disease characterized by inflammation and obliterative fibrosis of the bile ducts, leading to biliary cirrhosis and ultimately to liver failure. Four main clinical forms can be distinguished in children: i) neonatal SC, most probably a genetic disease transmitted by autosomal recessive inheritance; ii) SC associated with strong features of autoimmunity (referred as autoimmune sclerosing cholangitis) with quite good response to immuno-suppression iii) primary SC of unknown etiology (i...

Biliary atresia (BA) is a neonatal disorder characterized by aggressive fibroinflammatory obliteration of the biliary tract. Approximately 20 percent of BA patients demonstrate left-right laterality defects (syndromic BA). Cilia participate in important physiological functions in cholangiocytes, and as some ciliopathies have been associated with both laterality defects and hepatic fibrosis, we hypothesized that patients with syndromic BA exhibit abnormalities of cholangiocyte cilia that disrupt cholangiocyte homeostasis...

UNLABELLED: Neonatal ichthyosis and sclerosing cholangitis (NISCH) syndrome is a liver disease caused by mutations of CLDN1 encoding Claudin-1, a tight-junction (TJ) protein. In this syndrome, it is speculated that cholestasis is caused by Claudin-1 absence, leading to increased paracellular permeability and liver injuries secondary to paracellular bile regurgitation. We studied the role of claudin-1 in hepatic paracellular permeability. A NISCH liver and polarized rat cell lines forming TJs, the hepatocellular Can 10 and the cholangiocellular normal rat choloangiocyte (NRC), were used...

Neonatal ichthyosis-sclerosing cholangitis (NISCh) syndrome is a rare autosomal recessive disorder associated with scalp hypotrichosis, scarring alopecia, ichthyosis and sclerosing cholangitis. It is caused by homozygous mutations in the CLDN1 gene coding for the tight junction component claudin-1. Only five patients have been reported so far: four patients from two inbred Moroccan families, all carrying a dinucleotide deletion c.200_201delTT in the CLDN1 gene and a Swiss patient with a 1-bp deletion (c.358delG) in exon 2...

Alterations in bile secretion at the hepatocellular and cholangiocellular levels may cause cholestasis. Formation of 'toxic bile' may be the consequence of abnormal bile composition and can result in hepatocellular and/or bile duct injury. The canalicular phospholipid flippase (Mdr2/MDR3) normally mediates biliary excretion of phospholipids, which normally form mixed micelles with bile acids and cholesterol to protect the bile duct epithelium from the detergent properties of bile acids. Mdr2 knockout mice are not capable of excreting phospholipids into bile and spontaneously develop bile duct injury with macroscopic and microscopic features closely resembling human sclerosing cholangitis...

BACKGROUND: Endoscopic ultrasonography (EUS) is a less invasive modality and may be equal or superior to endoscopic retrograde cholangiopancreatography (ERCP) in visualizing the biliary tree. Its role and feasibility in children need to be accurately defined. AIM: This study aimed at evaluation of EUS in assessment of children with chronic liver disease (CLD) in comparison with ERCP. MATERIALS AND METHODS: The present study was carried out between September 2004 and February 2006 on 40 children suffering from CLD...

Claudin-1 (CLDN1) is a structural tight junction (TJ) protein and is expressed in differentiating keratinocytes and Langerhans cells in the epidermis. Our objective was to identify immunoreactive CLDN1 in human epidermal Langerhans cells and to examine the pattern of epidermal Langerhans cells in genetic human CLDN1 deficiency [neonatal ichthyosis, sclerosing cholangitis (NISCH) syndrome]. Epidermal cells from healthy human skin labelled with CLDN1-specific antibodies were analysed by confocal laser immunofluorescence microscopy and flow cytometry...
